PROPELLlNG-WHEEL.

SPECIFICATION forming part of Letters Patent No. 352,299, dated November9, 1886.

Application filed March 1, 1886.

.To aZZ whom it may concern:

Be it known that I, MosEs S. COLE, a citizen of the United States,residing in the city,

of Rivas, Republic of Nicaragua, Central America, have invented a newand Improved Propelling-Wheel, of which the following is a full, clear,and exact description.

The object of my invention is to provide a new and improvedpropelling-wheel which has its wings open through a certain part of itsrevolution and closed through the remainder of the same.

The invention consists of cams which, in connection with rotating spokesor arms, operate sliding bars which open the wings of the wheel during acertain part of a revolution and lock the same in this open position.

The invention also consists of various parts and details andcombinations of the same, as will be fully described hereinafter, andthen pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a partofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

. Figure 1 is a side elevation, with parts removed, of my improvedpropellingwheel.

Fig. 2 is a face view of one of the cams. Fig.

3 is'a sectional plan view of one arm and cam connections, showing thewings closed. Fig. 4 is a similar view showing the wings open; and Fig.5 is a cross-section on the line a; m, Fig. 4. Fig. 6 is a detailperspective view.

My improved propelling-wheel is specially adapted for aerial vesselssuch as are described in my application for Letters Patent filed withthis application; but it can also be used for propelling steamers andboats, or for fans or other purposes.

The brackets A A, carrying my propellingwheel B, are attached to thevessel or apparatus which is to be provided with my improvement. To theinside of each outer end of the brackets A is secured a cam, 0, having acam-groove, G, and an aperture, 0*,through which passes the shalt D,provided on its outer ends with crank-arms D, which are connected withthe driving machinery of the vessel or apparatus. Between the camsO isplaced a bracket-wheel, E, secured on the shaft D, so

as to rotate with the same when the latter is set in motion.

The bracket-wheel E is provided with two, three, four, or more spokes,E, from the end of each of which extends a wingarm, F. Each spoke E isprovided with a central aperture, E", and a side recess, E

'An arm or bar, G, having on its inner end a head, G, is mounted toslide in a recess, F, formed on the wing-arm F, and its head G passesinto the central aperture, E of its spoke E, and is held. in placetherein by the guidepins H and H, extending into the side recess, E Thepin H extends beyond the said side recess, E and passes into the groovesO of the cams O. The bar G is held in place in the recess F of thewing-arm F by the ,coverplates F On the face of the wingarm F, on eachside, are hinged the wings I, each of which consists of a frame, I,covered with canvas orother suitable material, and provided with two,three, or more lugs, 1 extending at right angles to the arm F when thewings I are open, and resting flat upon the face of the arm F when thewings I are closed.

Three or more wedge-shaped pieces, J J J', are secured to the upper edgeof the sliding bar G, and the center one, J, is provided with across-piece, J having on each end a beveled locking'piece, J, whichengages with a piece, 1 attached to the wing-frame I when the wing isclosed. The under side of the arm F is incased by a wedge-shaped cover,K, of sheet metal or other material, so as to present but littleresistance in passing through water or air.

The operation is as follows: The cam-groove O of the cam 0 consists ofthe part a, which is concentric with the aperture 0 and forms asemicirculargroove ofthe parts I) and b, which extend from the ends ofthe groove a at an angle of about forty-five degrees and continue intothe-concentric groove 0 in an angle of ninety degrees, so that therespective pins H of the sliding bars G enter alternately the parts a,b, c, and 1), whereby the bar G is moved toward or from the centralaperture, 0', of the cam C. This motion of the sliding bar G causes thewings I to open as soon as the pin H leaves the part a of the groove 0'and enters the part b,

and to open to the greatest extent when the pin enters the part 0,remaining open while the pin passes through the part c. The wings canbegin to close as soon as the pin H reaches the part b, and are free toclose entirely when the pin H enters the part a of the groove 0. Theclosing of the wings is accomplished by the resistance of the airthrough which the wings pass. A constant rotary motion is imparted tothe bracket-wheel E by the shaft D and its connection with the drivingmachinery attached to the vessel or apparatus to which my improved wheelis attached. The motion is in the direction of the arrow a. The rotation"of the bracket-wheel E causes the pins H, on

entering the parts b of the cam-grooves O, to

J pass over the pieces I when the wings are fully opened, and therebylock the same in this open position until the sliding bar G commences torecede from the axis of the shaft D, which is done as soon as the pins Henter the parts b of the grooves 0'. As soon as the pins H have reachedthe parts a of the grooves C, the wedge-shaped pieces J, J, and J 2 andlugs J are out of contact with the respective lugs l and thecross-pieces I of the wing-frames I, so that the wings I, being free toclose, are forced to a closed position by the resistance of the air withwhich they come in contact on the rotation of the bracket-wheel E, andremain closed until the pins H have traveled through the parts a of thegrooves, after which the opening and closing is again accomplished, asbe-' fore described. a

It will be seen that all the wings I, attached to their respective barsG, sliding in the spokes E of the bracket-wheel E, are alternatelyopened and closed by the action of the pin H in the groove 0 of the camG, and by the resistance of the air through which the wings pass.

- It will be seen, further, that the wings are open only throughonequarter of the entire revolution, and are completely closed throughone-half of a revolution of the bracketwheel E, the remainingone-quarter being necessary for the opening of the wings, as abovedescribed, and the closing of the same by the resistance of the air.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patentas shown and described.

2. In apropelling-wheel, the combination of a cam and a bracket-wheelhaving spokes each provided with a wing-arm, and wings hinged to thesaid arms and consisting of a frame covered with canvas and providedwith lugs, with a sliding bar provided with wedge-shaped pieces whichengage the logs on the wingframe, and provided with pins extendingintothe groove of the cam, substantially as herein shown and described.

3. In a propelling-wheel, the combination of a earn, a bracketwheelprovided with spokes, each having a wing-arm, and with wingshinged oneach arm and provided with lugs, with a sliding bar provided withwedgeshaped pieces, and a locking device consisting of lugs secured tothe sliding arm and passing over bars attached to the wing-frame, andwith pins extending into the groove of said cam, substantially as hereinshown and described.

4. 1n apropelling-wheeh the cams 0, having grooves O, the shaft D,provided with crankarms D, and the bracket-wheel E, provided with thespokes E and the arms F, in combination with the hinged wings I, havinglugs I, the sliding bar G, having wedge-shaped pieces J, J, and J whichengage with the lugs I of the hinged wings I and lockingpl'ates J, andthe pins H and H, substantially as herein shown and described.

5. In a propelling-wheel, the earn 0, having a cam-groove, O, thebracket-wheel E, provided with the spokes E, each having the aperture Eand recesses E the arms F, having recesses F, and the hinged wings I,each having a frame, I, provided with lugs I on pieces I, in combinationwith the sliding bars G, provided with the wedge-shaped pieces J JJ andlugs J, which engage with the lugs I" andthe pieces 1 respectively, ofhinged wings I, and the pins H and H, substantially as herein shown anddescribed.
